Tools don’t fly through the air and nothing gets broken at Lewiston Iron Inc. as Neal Gagne and Brian Blanchard reassemble a custom chopper for shop owner Don Dufour.

A slight grunt escapes Gagne as he hefts a 120-cubic-inch El Bruto motor onto the frame. Other than that, only light banter is heard in the spotless shop.

“What the Teutuls have done for custom bike building can’t be summed up in words,” says John “The Smooth” Smotherman as he films the assembly for “The Build: Motorcycle Television,” which airs at 9 p.m. Fridays on Time Warner’s Channel 9. “See, you can custom build a bike without the screaming and ego tantrums like on the O.C.C.”

“The Smooth” is referring to the popular cable TV show “American Chopper,” which features Paul Sr., Paul Jr. and Mike Teutul of Orange County Choppers. The show raised the popularity of custom motorcycles when it debuted in 2002 with Paul Sr.’s random destruction and verbal debates with his sons and crew.

The crew at Lewiston Iron Inc. has been modifying bikes much of their lives. Gagne built his first bike 20 years ago. Blanchard started dabbling more than seven years ago.

“We get bored, so we have to build toys,” Gagne says with a laugh. “We do this more as a hobby than as a living. Custom bike-building doesn’t pay. There aren’t too many people lining up with $50,000 to have a bike built.”

Their current project would sell for $55,000 to $60,000. This is the bike’s second paint job – the first ended up blistering within months of being finished – and the first bike the crew has worked on together.

The frame, wheels, seat, motor and basic drive train elements were the only parts purchased for the bike. All other parts and accessories were manufactured in Lewiston.

The macabre scenes adorning the bike were hand-painted by Glenn Chadbourne of Newcastle and each person who’s worked on the bike has been immortalized with their names painted on tombstones. Gagne built up the clear coat layer by layer, ending in a smooth, glass-like finish.

“The good thing about having a bike built is you get it your way,” he says.
